Abstract

[0002] With the widespread adoption of automated packaging equipment, heat-sealing packaging bag sealing devices are widely used in production lines in the food and pharmaceutical industries. Traditional sealing equipment typically employs a fixed-spaced sealing component structure, using a cylinder to drive the entire assembly for pressing. However, due to the fixed spacing of the sealing components, existing technologies require the equipment to complete a full stroke for each sealing operation, which cannot match the pace of high-speed production lines. Furthermore, the sealing components are often arranged horizontally, making it inconvenient to seal bags filled with materials. Utility Model Content

[0053] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0054] Figures 1-4 This diagram illustrates a structural diagram of a packaging bag sealing device according to an embodiment of this application. Figures 1-4 As shown, the sealing device may include:
[0055] Bracket 100;
[0056] The first sealing component 200 is disposed on the bracket 100;
[0057] The second sealing component 300 is disposed on the bracket 100, and the first sealing component 200 is disposed opposite to the second sealing component 300.
[0058] The drive assembly 400 is mounted on the bracket 100 and drives the first sealing assembly 200 and the second sealing assembly 300 to move in opposite directions.
[0059] In this embodiment, the first sealing component 200 and the second sealing component 300 are driven to move along the bracket 100 by the driving component 400. The driving component 400 drives the first sealing component 200 and the second sealing component 300 to move in opposite directions, thereby changing the distance between the first sealing component 200 and the second sealing component 300. When sealing, the external clamping device clamps the packaging bag and transports it between the first sealing component 200 and the second sealing component 300. The driving component 400 drives the first sealing component 200 and the second sealing component 300 to clamp the packaging bag and heat the packaging bag to seal it, thereby completing the sealing of the packaging bag.
[0060] The drive component 400 facilitates the adjustment of the distance between the first sealing component 200 and the second sealing component 300, thereby enabling rapid sealing of the packaging bag in conjunction with external equipment. The drive component 400 drives the first sealing component 200 and the second sealing component 300 to move, reducing their movement distance. The first sealing component 200 and the second sealing component 300 are suspended by the bracket 100, facilitating vertical packaging of the packaging bag, preventing spillage of materials inside the packaging bag, and adopting a one-bag-one-close method to reduce the error rate of sealing the packaging bag and improve the sealing efficiency of the packaging bag.
[0061] like Figures 1-4 As shown, in one embodiment, it further includes:
[0062] The sensing component 500 is mounted on the bracket 100 and senses the position of the first sealing component 200.
[0063] The packaging bag inlet 600 is mounted on the bracket 100, and its position corresponds to the contact position between the first sealing component 200 and the second sealing component 300.
[0064] In this embodiment, the movement distance of the first sealing component 200 is sensed by the setting of the sensing component 500, and the movement stroke of the driving component 400 is controlled by the sensing component 500. The sensing component 500 only needs to be set on one side. The first sealing component 200 and the second sealing component 300 move in opposite directions simultaneously under the action of the driving component 400. Therefore, the sensing component 500 only needs to be set on one side.
[0065] Specifically, the sensing component 500 is a common distance sensor on the market, which is connected through a PCB board and connected to the driving component 400 through the PCB board, thereby controlling the driving component 400 through the PCB board;
[0066] The packaging bag inlet 600 is adjustablely mounted on the bracket 100. Specifically, the packaging bag inlet 600 consists of two limiting plates. The ends of the two limiting plates away from the support plate 110 have inclined portions, forming an obtuse angle between the inclined portions and the limiting plates. The packaging bag enters the limiting plates through the inclined portions, which helps to tidy up the sealing end of the packaging bag, making it easier for the first sealing component 200 and the second sealing component 300 to seal the bag.
[0067] The position of the packaging bag inlet 600 corresponds to the position of the closed part of the first sealing component 200 and the second sealing component 300. The position of the external clamping device is set according to the position of the packaging bag inlet 600. The external clamping device clamps the packaging bag and rotates it into the packaging bag inlet 600. After the packaging bag inlet 600 tidies up the sealing part, the first sealing component 200 and the second sealing component 300 seal the bag.
[0068] like Figures 1-4 As shown, in one embodiment,
[0069] The bracket 100 includes:
[0070] The support plate 110, the sensing component 500 and the packaging bag inlet component 600 are all mounted on the support plate 110;
[0071] The slide rail 120 is mounted on the support plate 110, and the first sealing assembly 200 and the second sealing assembly 300 slide along the slide rail 120 relative to the bracket 100.
[0072] In this embodiment, the first sealing assembly 200 and the second sealing assembly 300 slide along the slide rail 120;
[0073] Specifically, the slide rail 120 has an inverted "T" shaped cross-section, and the first sealing component 200 and the second sealing component 300 have grooves that are adapted to the slide rail 120, thereby ensuring the stability of the first sealing component 200 and the second sealing component 300 during operation.
[0074] like Figures 1-3 As shown, in one embodiment,
[0075] The first sealing component 200 includes:
[0076] The first slider 210 is driven by the drive component 400 to move along the slide rail 120, and the first slider 210 corresponds to the sensing component 500;
[0077] The first sealing element 220 is disposed on the first slider 210.
[0078] In this embodiment, the first slider 210 has a groove that is adapted to the slide rail 120, and the first sealing member 220 is a common sealing device on the market, which seals the packaging bag by heating.
[0079] like Figures 1-3 As shown, in one embodiment,
[0080] The second sealing component 300 includes:
[0081] The second slider 310 is driven by the drive assembly 400 to move along the slide rail 120;
[0082] Second sealing piece 320;
[0083] At least one guide rod 330 is disposed at the second sealing member 320. One end of the guide rod 330 away from the second sealing member 320 passes through the second slider 310. The second sealing member 320 is located on the side of the second slider 310 facing the first sealing member 220.
[0084] At least one spring 340 is disposed between the second sealing member 320 and the second slider 310.
[0085] In this embodiment, the second slider 310 has the same structure as the first slider 210. The first slider 210 and the second slider 310 are driven by the driving component 400 to change the distance between the first sealing member 220 and the second sealing member 320. The packaging bag is clamped and heated by the first sealing member 220 and the second sealing member 320, thereby sealing the packaging bag.
[0086] Furthermore, a guide rod 330 and a spring 340 are provided between the second sealing member 320 and the second slider 310. When the first sealing member 220 and the second sealing member 320 come into contact, the spring 340 contracts and applies an opposite force to the second sealing member 320, thereby clamping the first sealing member 220 and the second sealing member 320 together.
[0087] Furthermore, the guide rod 330 and the spring 340 can also be provided on the first sealing member 220, or the guide rod 330 and the spring 340 can be provided on both the first sealing member 220 and the second sealing member 320;
[0088] Specifically, the first sealing component 220 and the second sealing component 320 have the same structure. They are both common sealing devices on the market, which seal the packaging bag by heating.
[0089] The guide rod 330 is disposed on the second sealing member 320, and the second slider 310 has a through hole adapted to the guide rod 330. The movement trajectory of the second sealing member 320 is limited by the setting of the guide rod 330.
[0090] Specifically, the optimal number of guide rods 330 is two to ensure the stability of the second sealing component 320's movement;
[0091] The preferred number of springs 340 is three. When the first sealing member 220 and the second sealing member 320 come into contact, the springs 340 contract and apply an opposite force to the second sealing member 320, thereby clamping the first sealing member 220 and the second sealing member 320 together.
[0092] like Figure 4 As shown, in one embodiment,
[0093] Driver component 400 includes:
[0094] Drive motor 410;
[0095] Rotating component 420 is mounted on support plate 110, and drive motor 410 drives rotating component 420.
[0096] Two swing arms 430, one end of each swing arm 430 is mounted on the rotating member 420, and the ends of the two swing arms 430 away from the rotating member 420 are respectively mounted on the first slider 210 and the second slider 310. When the rotating member 420 rotates, the two swing arms 430 drive the first slider 210 and the second slider 310 to move in opposite directions respectively.
[0097] In this embodiment, the drive motor 410 drives the rotating component 420 to rotate. While the rotating component 420 rotates, the two swing arms 430 rotate accordingly. Since the ends of the two swing arms 430 away from the rotating component 420 are respectively rotatably connected to the first slider 210 and the second slider 310, when the rotating component 420 rotates, the drive swing arms 430 drive the first slider 210 and the second slider 310 to move relative to the support plate 110.
[0098] The output shaft of the drive motor 410 is connected to the rotating component 420 via a connecting shaft. When the output shaft of the drive motor 410 rotates, the drive connecting shaft drives the rotating component 420 to rotate.
[0099] Specifically, the cross-section of the swing arm 430 is arc-shaped.
[0100] like Figure 4 As shown, in one embodiment,
[0101] The rotating member 420 has two protrusions, and one end of each of the two swing arms 430 is respectively disposed on the corresponding protrusion.
[0102] In this embodiment, the protrusion facilitates the rotatable member 420 to be rotatably connected to the two swing arms 430, thereby facilitating the movement of the swing arms 430.
